1. Technical SEO Setup

Start by laying a strong technical foundation for your website.

2. Keyword Research & Search Intent

Understand what your audience is searching for and align your content accordingly.

  • Identify primary keywords for each key page.
  • Use keyword research tools to find long-tail and related keywords.

3. On-Page SEO Essentials

Optimize every page on your website to help search engines and users understand your content.

4. Content Strategy Essentials

Create and organize content that solves real problems and earns visibility.

  • Publish at least 3–5 high-quality blog posts or pillar articles.

  • Use a content calendar to plan and maintain consistency.
  • Include strong calls-to-action (CTAs) to guide users.

  • Update older content regularly to keep it fresh and competitive.

5. Local SEO (If Applicable)

Optimize for local search visibility if you’re targeting a specific area.

  • Use local business schema to help search engines understand your location.
  • Encourage and respond to customer reviews on Google and other platforms.

6. Indexing & Crawl Management

Ensure search engines can crawl and index your website correctly.

  • Use Search Console to inspect whether key pages are indexed.
  • Block low-value pages from indexing (e.g., login, admin, filters) using noindex or robots.txt.
  • Add canonical tags to avoid duplicate content issues.
  • Fix crawl errors and resolve soft 404s or blocked resources.
